Method of delivering a withdrawal cord to a substrate

ABSTRACT

A method of delivering a withdrawal cord to a transfer member, wherein the method includes providing a supply path fluidly connected to a metered cord supply. The supply path comprises a pressure source, a transfer member, and a cutting apparatus. The transfer member comprises a first surface, a second surface, and a plurality of orifices on the first surface. The method also comprises moving a deployed cord supply towards the transfer member through the supply path by a fluid flow generated by the pressure source. The method further comprises moving a portion of the deployed cord supply into an orifice of the transfer member, moving the deployed cord supply to an attachment system, connecting the deployed cord supply to a substrate, and cutting the deployed cord supply to create a withdrawal cord comprising a first end and a second end; wherein a portion of the withdrawal cord is in the orifice to the transfer member.

FIELD OF INVENTION

The present disclosure relates to a method for delivering a withdrawal cord to a transfer member, and more particularly, to a method for delivering a withdrawal cord to an attachment system utilizing fluid flow in a supply path.

BACKGROUND OF THE INVENTION

Withdrawal cords are commonly sewn onto tampons to help ease in the removal of the tampon from the vaginal cavity. Typically, during the manufacturing process, a continuous cord is sewn onto multiple pledgets thereby connecting the pledgets. The pledgets may be spaced on a conveyor connected by the continuous cord. The amount of cord between two pledgets may comprise the amount of cord that is not sewn to the pledget, which represents the graspable portion of a withdrawal cord. The cord is then cut between pledgets in a separate process; leaving a portion of the cord attached to the pledget prior to the location of the cut and portion of the cord attached to a pledget after the location of the cut. The typical process also sews the cord onto the entire longitudinal length of the pledget. This leads to unnecessary sewing that utilizes excess sewing thread and cord. This process also creates inefficiency because the conveyor must space the pledgets to account for the desired length of cord between pledgets.

The typical process ideally cuts the cord without cutting any of the pledgets. However, often, one or more pledgets are partially cut when cutting the cord. This leads to irregular pledgets that are discarded because they do not meet the product target.

Therefore, it would be desirable to provide a method and apparatus for delivering a withdrawal cord to an attachment system. The transfer member may move the cord supply to an attachment system capable of attaching a single withdrawal cord to a pledget. Upon contacting the pledget, the cord supply may be cut to form a withdrawal cord. This allows for a reduced sewing requirement per pledget while possibly increasing the pledget production rate.

SUMMARY OF THE INVENTION

A method of delivering a withdrawal cord to an attachment system, wherein the method includes providing a supply path fluidly connected to a metered cord supply. The supply path comprises a pressure source, a transfer member, and a cutting apparatus. The transfer member comprises a first surface, a second surface, and a plurality of orifices on the first surface. The method also comprises moving a deployed cord supply towards the transfer member through the supply path by a fluid flow generated by the pressure source. The method further comprises moving the deployed cord supply into an orifice of the transfer member, moving the transfer member orifice to an attachment system, wherein the attachment system attaches the end of the cord supply to a substrate, and cutting the cord supply to form a withdrawal cord partially attached to a substrate comprising a first end and a second end; wherein a portion of the withdrawal cord is in the orifice to the transfer member.

The present disclosure relates to a method for delivering a withdrawal cord to a transfer member utilizing fluid flow in a supply path. Once delivered, an orifice on the transfer member may move out of a fluid flow and deliver the withdrawal cord to an attachment system. The withdrawal cord may be attached onto a substrate, such as, for example, a pledget. The apparatus may be timed with a conveyor that delivers the pledgets such that each withdrawal cord is delivered to a pledget.

In an exemplary configuration, a metered cord supply may advance a deployed cord supply to a supply path. The supply path is fluidly connected to the metered cord supply and comprises a transfer member, a transfer tube and a cutting apparatus. The transfer member comprises a first surface, a second surface, and an orifice in the transfer member first surface. The supply path contains a fluid flow capable of carrying a deployed cord supply. The fluid flow may be created by positive pressure, negative pressure, or combinations thereof. The fluid flow is directed to deliver the deployed cord supply to the transfer member abutting the cutting apparatus. The transfer member then moves the deployed cord supply to an attachment system, wherein the attachment system connects the end of the deployed cord supply to a substrate. In such an exemplary configuration, the cutting apparatus may be configured to cut a set amount of cord once the deployed cord supply is connected to a substrate. Cutting the deployed cord supply creates a withdrawal cord. At least a portion of the withdrawal cord is within the orifice of the transfer member.

In an exemplary configuration, a metered cord supply advances a deployed cord supply to a supply path. The supply path is fluidly connected to the metered cord supply and comprises a transfer member, a transfer tube and a cutting apparatus. The transfer member comprises a first surface, a second surface, and an aperture through the transfer member connecting the first surface to the second surface. The supply path contains a fluid flow capable of carrying a deployed cord supply. The fluid flow may be created by positive pressure, negative pressure, or combinations thereof. The fluid flow is directed to deliver the deployed cord supply to the transfer member first surface abutting the cutting apparatus. The transfer member then moves the deployed cord supply to an attachment system, wherein the attachment system connects the end of the deployed cord supply to a substrate. In such an exemplary configuration, the fluid flow is created by negative pressure from a vacuum source within a receiving chamber that abuts the second surface of the transfer member. The cutting apparatus may be configured to cut a set amount of cord once the deployed cord supply connects with a substrate. Cutting the deployed cord supply creates a withdrawal cord. At least a portion of the withdrawal cord is within the aperture of the transfer member.

In an exemplary configuration, a metered cord supply advances a deployed cord supply to a supply path. The supply path is fluidly connected to the metered cord supply and comprises a transfer member, a transfer tube and a cutting apparatus. The transfer member comprises a first surface, a second surface, and an aperture through the transfer member connecting the first surface to the second surface. The supply path contains a fluid flow capable of carrying the deployed cord supply. The fluid flow is created by negative pressure from a vacuum source within a receiving chamber that abuts the second surface of the transfer member. The fluid flow is directed to deliver the metered supply cord to the transfer member first surface abutting the cutting apparatus. The deployed cord supply enters the aperture in the transfer member. The transfer member then moves the deployed cord supply to an attachment system, wherein the attachment system connects the end of the deployed cord supply to a substrate. The cutting apparatus cuts the deployed cord supply once the deployed cord supply contacts a substrate to form a withdrawal cord. The transfer member aperture moves out of the fluid flow taking the withdrawal cord.

The receiving chamber second end wall may comprise an outlet and a tunnel. The receiving chamber outlet deflects the deployed cord supply, whereby the cord is forced upon the transfer member second surface.

The transfer member, cutting apparatus, attachment system, and a metering system may work in unison to deliver a withdrawal cord to each orifice of the transfer member. The transfer member, cutting apparatus, and metering system may work in unison to deliver a withdrawal cord of any length. Alternatively, the transfer member, cutting apparatus, and metering system may be set to work in unison to deliver a withdrawal cord at a set rate, such as, for example, to deliver deployed cord to the orifices at any desired pattern, such as, for example, every other orifice. Alternatively, the transfer member, cutting apparatus, and metering system may each be controlled as an individual unit to control withdrawal cord delivery by speeding up or slowing down one or two units while maintaining the other unit(s) constant. In a configuration, the maximum velocity of the apparatus may be limited by the rate at which the attachment system may attach a withdrawal cord to a substrate, such as, for example, the rate at which a sewing machine can sew the withdrawal cord.

The cord delivery system may comprise a cord supply and a metering system. The metering system directs an end of a deployed cord supply into a supply path. The metering system may comprise any metering system suitable for feeding a cord into a system, such as, for example, an apron roll or an omega roll. The metering system may comprise two rolls working in unison to direct the cord to the supply path. The metering system controls the deployed cord supply length delivered to the cutting apparatus. The metering system may be used as a phasing apparatus to control withdrawal cord position, wherein the cord has a distinguishing feature, such as, for example, a slub or a change in color.

The apparatus comprises a transfer member connected to a cutting apparatus. The cutting apparatus is connected to a transfer tube. The transfer tube is connected to a cord delivery system. The transfer member, cutting apparatus, and the transfer tube form a supply path for the deployed cord supply from the cord delivery system.

The supply path may contain a pressure source that creates a fluid flow directed towards the transfer member. The fluid flow may carry a cord. The fluid flow may comprise any medium capable of carrying a cord, such as, for example, air. The fluid flow may be created by one or more pressure sources that generate fluid movement, such as, for example, a positive displacement pump, a blower, a vane pump, and a venturi device.

The fluid flow may be created by positive pressure, negative pressure, and combinations thereof. Positive pressure may be introduced into the supply path at the inlet of the transfer tube. Positive pressure may be introduced before the metering system provided that the metering system forms part of the fluid flow path. Changes in pressure may be introduced at any point along the supply path provided that the pressure does not contradict the fluid flow direction.

Negative pressure may be created by a vacuum source connected to a receiving chamber abutting the second surface of the transfer member. The fluid flow velocity must exceed the required cord velocity in the supply path. The required cord velocity is determined by the desired length of a withdrawal cord. The required fluid flow velocity will vary depending on the cord material, the desired length of the withdrawal cord, and any fluid flow losses or restrictions in the supply path. The fluid flow velocity should not be capable of damaging the supply cord.

Under negative pressure, the fluid flow velocity may be maintained between a vacuum source and the cord delivery system such that the fluid flow velocity exceeds the cord velocity in the supply path by the apertures in the transfer member or by a combination of a hole and the aperture in the transfer member body comprising one aperture. Under negative pressure only, the vacuum should be at least ten inches of water.

To maintain the fluid flow velocity, the supply path should minimize the number of bends, restrictions, and pressure leaks. Bends in the supply path create pressure drops and may increase turbulence at particular portions of the supply path leading to reduced fluid flow velocity. Similarly, any leaks in the supply path will lead to a reduced fluid flow velocity. Leaks may be reduced, if not eliminated, by choosing the appropriate materials so that a seal will exist between the opening to the cutting apparatus and the transfer member and between the transfer member and the receiving chamber. Compatible materials may allow for a constant seal while still allowing the transfer member to bisect the fluid flow without adverse friction. In a non-limiting configuration, the transfer member comprises stainless steel and the cutting apparatus opening and the receiving chamber opening comprise nylon. Similarly, a tight seal should exist between the transfer tube and the cutting apparatus.

Without being bound by theory, it is believed that utilizing a fluid flow allows the cord supply to follow the fluid flow created by the positive or negative pressure into an orifice of the transfer member. This allows for a fluid flow that adapts to the position of the orifice in the supply path. The cord supply comprises a flexible cord that may follow the fluid flow to the orifice within the supply path. Without being bound by theory, it is believed that enabling the flexible cord to follow the fluid flow allows for a faster production of withdrawal cords.

Allowing the flexible cord to follow the fluid flow allows a cord to enter an orifice in the transfer member while moving the transfer member orifice. This may increase the throughput of withdrawal cords to a transfer member.

The transfer member may comprise any tangible body that is capable of receiving an end of a deployed cord supply, capable of moving the deployed cord supply, capable of moving a withdrawal cord, and that does not inhibit the fluid flow velocity. The transfer member comprises one or more orifices on the first surface that receive the deployed cord supply first end. The one or more orifices may be, for example, apertures that connect the transfer member first surface to the transfer member second surface or cavities with additional fluid channels that do not restrict the fluid flow, while restricting the first end of the deployed cord supply. In a non-limiting configuration, one or more apertures may each contain an obstruction that prevents the deployed cord supply from crossing the second surface of the transfer member without inhibiting the fluid flow velocity.

In a non-limiting configuration, the transfer member may comprise a unitary body in the form of a ring with a plurality of orifices that are equidistantly spaced along a rim abutting the perimeter of the transfer member, a closed chain of segments wherein each segment comprises an orifice, or a body with one orifice and a hole. In a non-limiting configuration, the first surface of the transfer member is proximal to a cutting apparatus and distal to an optional receiving chamber. In a non-limiting configuration, the second surface of the transfer member is proximal to an optional receiving chamber and distal to a cutting apparatus.

The transfer member may comprise a unitary body in the form of a ring with a plurality of orifices in the form of apertures that are equidistantly spaced along a rim abutting the perimeter of the transfer member. The ring comprises a central axis. The transfer member central axis may or may not be vertical or horizontal. The rigid body of the transfer member may be connected to the central axis by one or more spokes.

Alternatively, the transfer member may comprise a closed chain of segments wherein each segment comprises an orifice in the form of an aperture. The closed chain comprises two or more segments connected to each other, to a common axis, or a combination thereof. The transfer member segments move their respective orifices through the fluid flow, receive the withdrawal cord, and deliver it to the attachment system.

The segments comprise a first surface, a second surface, a front end, a back end, a width defined by the distance between the first surface and the second surface, a height, and a length. The height and length of the segment define a first surface area of the segment on the first surface and a second surface area of the segment on the second surface. The second surface height may be different than the first surface height making the first surface area a different dimension from the second surface area. The segments may be connected in a rigid closed structure, such as, for example, a ring or in a non-rigid closed structure, such as, for example, a closed serpentine chain. The two or more segments are connected such that the front end of a segment is connected to the back end of a second segment. In a rigid body, the one or more segments comprise a rim defined by the first surface area and the second surface area of the segments. The segment comprises an aperture that connects the first surface and the second surface.

The transfer member may comprise a body with one aperture. The body with one aperture has a length which is at least the width of the aperture plus the width of the greater of the two openings abutting the first surface and the second surface of the body. The body with one aperture reciprocates along a line or arc that moves the aperture through the fluid flow. The body with one aperture may comprise an additional hole which connects the first surface of the body to the second surface of the body. The additional hole serves to maintain a fluid flow between the cord supply and the receiving chamber when the aperture is outside the fluid flow.

The transfer member that is a body with one aperture reciprocates along a line or arc that moves the aperture through the fluid flow. The aperture may receive the cord supply at any point wherein the aperture is in the fluid flow. The cutting apparatus cuts the cord supply creating a withdrawal cord. The aperture moves out of the fluid flow to deliver the withdrawal cord to the attachment system. The additional hole may maintain the fluid flow while the aperture is outside of the fluid flow.

The transfer member may comprise protuberances that extend from the width of the transfer member between the first surface and the second surface. The protuberances may extend from either width.

The apertures may be between about 4 mm² and 100 mm², such as, for example, 50 mm², 40 mm², 30 mm², 20 mm², and 10 mm². The apertures may be tapered from a larger opening on the first surface to a smaller opening on the second surface. The large opening on the first surface increases the target for the deployed cord supply. The smaller opening on the second surface increases positional control of the withdrawal cord first end. Tapering allows increased air flow velocity through the aperture in the small end of the aperture compared to the large end.

In a non-limiting configuration wherein the attachment system is on the second surface of the transfer member, the width of the transfer member may not be greater than the length of the withdrawal cord. In a non-limiting configuration, the width of the transfer member may not be less than half of the difference between the unsewn cord length and the pitch of the apertures in the transfer member. If the width of the transfer member is less than the cord length minus the pitch of the apertures in the transfer member, a second end of the withdrawal cord may enter the receiving chamber through the aperture following the aperture containing the first end of the withdrawal cord. This may cause the same withdrawal cord to be sewn onto two pledgets.

In a non-limiting configuration, wherein the transfer member comprises a rigid body comprised of segments that rotate about the central axis of the rigid body, the transfer member may be held by three or more support wheels. The three support wheels may be in a triangle configuration. Alternatively, the transfer member may be held by four support wheels in a square configuration. In a non-limiting configuration, the rigid ring of segments may be rotated by a belt which is connected to a drive wheel.

The cutting apparatus comprises a cutting implement enabled to sever the deployed cord supply to form a withdrawal cord, such as, for example, a rigid knife, a laser, a rotary knife, a flexible knife, a guillotine, or a blade. In an exemplary configuration, a knife is attached to a rotary axis that rotates the knife through the supply path. A pressure surface, such as, for example, a rotating anvil, may be located opposite the knife The knife may contact the pressure surface, severing the cord supply.

In a non-limiting configuration, the cutting apparatus comprises a volumetric space joining the point at which the knife crosses the supply path and the transfer member. The volumetric space allows for a smooth transition between the point at which the knife crosses the supply path and the opening that abuts the transfer member with minimal increase in cross section area to maintain fluid flow velocity.

The opening is formed by a first edge, a second edge, a top wall connecting the first edge to the second edge, and a bottom wall connecting the first edge to second edge.

If the opening has a length greater than one pitch of the apertures on the transfer member plus one width of the apertures, then the end of a first withdrawal cord may enter the aperture for the second cord and/or the beginning of the second cord may enter the aperture of the first withdrawal cord.

The cutting apparatus may comprise an alternative fluid flow path when the knife rotates through the supply path. The alternative fluid flow path ensures that a fluid flow exists when the knife bisects the fluid flow path taken by the deployed cord supply. The alternative fluid flow path may be formed by a gap between the rotary axis for the knife and a casing for the knife When the knife does not bisect the deployed cord supply fluid flow path, this alternative fluid flow path is blocked by the knife.

When the transfer member comprises more than one segment or is a rigid ring, the cutting apparatus opening may be less than the area of the abutting first surface of a segment of the transfer member or a pitch of the rigid ring and the cutting apparatus opening follows the line of motion of the aperture of the transfer member. The length of the cutting apparatus opening must be greater than the length of the segment.

Alternatively, when using a transfer member body comprising a single aperture, the cutting apparatus opening may be less than the area of the first surface of the transfer member body. The cutting apparatus opening length must be greater than the width of the hole plus the distance between the hole and the aperture.

The transfer tube may comprise an inlet in proximity or abutting the metering system of the cord delivery system and an outlet that is in direct contact with the cutting apparatus. The transfer tube may be made of any material that can sustain a tubular form under the required amount of negative pressure, positive pressure, or combinations thereof, such as, for example, stainless steel and polycarbonate.

The transfer tube may be any suitable diameter, such as, for example, 1 mm to 20 mm, such as, for example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 15 mm. The transfer tube should have the least number of bends possible to reduce the loss of air velocity in the transfer tube.

The metered cord supply comprises a metering system and a cord supply. The metering system may comprise any suitable feed mechanism, such as, for example, an omega roll, an apron roll, or a two roll nip. The metering system controls the rate at which the cord supply is deployed to the supply path. In an exemplary configuration, the metering system comprises an apron roll and a drive wheel.

The cord supply can comprise any suitable material, including for example, cotton, cellulose, rayon, polyolefins such as, for example, polyethylene or polypropylene, nylon, silk, polytetrafluoroethylene, wax, Teflon, or any other suitable materials.

The cord supply may be non-absorbent along at least the location of attachment to the pledget. As used herein, the term “non-absorbent” refers to a structure that does not retain a significant portion of deposited fluid in its structure. The entire cord may be made non-absorbent, if desired. The materials comprising the cord may be inherently non-wettable or hydrophobic, or they may be treated to provide such properties. For example, a coating of wax may be applied to the cord to decrease or eliminate its absorbency. The cord need not necessarily be non-wicking, even if a non-absorbent cord is desired.

The cord supply can be formed by any suitable formation method and in any suitable configuration, such as, for example, one or more cords, strings, finger covers, ribbons, an extension of a material of the device, or combinations thereof.

The cord supply may alternate between a distinguishing feature and a length of plain cord. One withdrawal cord may be made up of a distinguishing feature and one or more lengths of plain cord. The distinguishing feature may be a slub. The slub may be attached onto the pledget. The length of plain cord may extend beyond the pledget. The length of the slub and the length of the plain cord are predetermined in the cord supply. The cord supply may comprise a continuous cord that alternates between slubs and non-slub portions or lengths of plain cord.

The withdrawal cord may be any suitable length, such as, for example, 200 mm or less, 150 mm or less, 100 mm or less, such as for example, 90 mm, 80 mm, 70 mm, 60 mm, 50 mm, 40 mm, 30 mm, 20 mm, 10 mm, 9 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, 3 mm, 2 mm, or 1 mm. The slub may be any suitable length, such as, for example, 100 mm or less, such as for example, 50 mm, 45 mm, 40 mm, 35 mm, 30 mm, 25 mm, 20 mm, 15 mm, 10 mm, 5 mm, 4 mm, 3 mm, 2 mm, or 1 mm. The slub may be a percentage of the total withdrawal cord length, such as, for example, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, or 5%.

The cord supply may be wound around any volumetric shape wherein the cord makes the outer surface of the shape, such as, for example, a cone, a spool, a cylinder, or a bobbin. The cord supply may be wound around two fixed ends of a tangible shape. Alternatively, the cord supply may be layered such that it rests upon itself.

In a non-limiting configuration, the deployed cord supply is forced to contact the transfer member by one or more physical constraints, one or more intangible constraints, or combinations thereof. Without being bound by theory, it is believed that forcing the deployed cord supply to contact the transfer member allows for better withdrawal cord control. Forcing the withdrawal cord to contact the transfer member enables the transfer member to transfer the withdrawal cord out of the fluid flow to the attachment system. The type of physical or intangible constraint may determine the distance that can be covered by the transfer member.

In a non-limiting configuration, an intangible constraint comprising one or more additional pressure sources may be used to force the deployed cord supply to contact the transfer member, creating friction between the deployed cord supply or the withdrawal cord and the transfer member. In an exemplary configuration, the intangible constraint may comprise a vacuum source within the transfer member enabled to create a vacuum against the first surface, second surface, or within the orifice of the transfer member.

In a non-limiting configuration, the transfer member may comprise an active clamp configured to grip the deployed cord supply or withdrawal cord inside the orifice of the transfer member. The active clamp may be spring loaded. The active clamp may force a portion of the withdrawal cord to contact an inner surface of the orifice. The active clamp may retract to release the withdrawal cord upon reaching the attachment system.

The apparatus may comprise a receiving chamber. The receiving chamber may comprise any suitable volumetric space comprising at least two openings to the volumetric space. In a non-limiting configuration, the receiving chamber has an opening comprising a first end wall, a second end wall, a bottom wall connecting the first end wall and the second end wall, and a top wall connecting the first end wall and second end wall. The receiving chamber may be tapered.

When deployed to vacuum, the receiving chamber comprises a back wall enclosing the receiving chamber and an opening to the vacuum source. The opening to the vacuum source may be located anywhere in the receiving chamber. The receiving chamber opening is formed by a first end wall, a second end wall, the bottom wall, and the top wall. The receiving chamber opening should be an area that allows for a continuous fluid flow through the transfer member. If the opening does not enable a continuous fluid flow, the fluid flow can pulse.

Alternatively, when deployed to vacuum, the receiving chamber may be any volumetric geometry provided that the opening to the receiving chamber comprises an opening with an arc-shaped slot, comprising a first end wall and a second end wall, whose radius is concentric and equal to the radius passing through the centers of the openings on the rim of the ring shaped transfer member. The arc-shaped slot may have a length equal to one pitch of the apertures on the transfer member plus or minus the width of an aperture.

The second end wall may comprise an outlet abutting the transfer member. The outlet may have a cross section area between 0.5 mm² to 30 mm². The outlet may pinch the withdrawal cord as it exits the receiving chamber by forcing it to come into contact with the rim of the second surface of the transfer member.

A tunnel may be joined to the receiving chamber at the outlet. Alternatively, a tunnel may be integral with the receiving chamber at the outlet. The integral tunnel may be a separate piece that connects to the opening of the receiving chamber and contacts the transfer member acting as the opening to the receiving chamber with a tunnel at the second end wall outlet. The tunnel can be of any suitable length such as, for example, 1 mm to 40 mm.

The receiving chamber may have a vacuum source. The vacuum source may draw between about 10 inches of water and about 80 inches of water, such as, for example, 30 inches of water, 35 inches of water, 40 inches of water, 45 inches of water, 50 inches of water, 55 inches of water, 60 inches of water, 65 inches of water, 70 inches of water, or 75 inches of water.

The attachment system may be any system capable of joining the deployed cord supply to a substrate. The attachment system is downstream of the supply path. However, the distance between the attachment system and the cutting apparatus is less than or equal to the desired length of a withdrawal cord. The attachment system may abut the first surface or the second surface of the transfer member. The attachment system may abut the supply path. The attachment system may comprise any known means of attachment, such as, for example, a sewing apparatus, an adhesive, ultrasonics, heat, a stapling device, or combinations thereof.

The attachment system may be a sewing apparatus. The substrate may be moved along the stitch plate by a star wheel, by a set of protuberances on the transfer member rim, the sewing apparatus, and combinations thereof. The sewing apparatus may be configured to sew the withdrawal cord to a substrate by any number of desired stitches for a length of withdrawal cord.

The substrate may be a pledget. The pledget may comprise rayon, cotton, or combinations of both materials. These materials have a proven record of suitability for use in the human body. The rayon used in the absorbent material may be any suitable type typically used in disposable absorbent articles intended for in vivo use. Such acceptable types of rayon include GALAXY Rayon (a tri-lobed rayon structure) available as 6140 Rayon from Acordis Fibers Ltd., of Hollywall, England. SARILLE L Rayon (a round fiber rayon), also available from Acordis Fibers Ltd. is also suitable. Any suitable cotton material may be used in the absorbent material. Suitable cotton materials include, long fiber cotton, short fiber cotton, cotton linters, T-fiber cotton, card strips, and comber cotton.

In a non-limiting configuration, a pledget may advance in a machine direction along a conveyor track to the sewing apparatus that engages the withdrawal cord. The pledget may be oriented such that the first end is perpendicular with the machine direction. In such a non-limiting configuration, the withdrawal cord sewing apparatus may be configured to sew a portion of a single withdrawal cord to the pledget. The sewn portion of the single withdrawal cord may be sewn along the longitudinal axis of the pledget in the first end of the pledget. Alternatively, the sewn portion of the single withdrawal cord may be sewn along the longitudinal axis of the pledget in the middle section. The single withdrawal cord extends beyond the pledget. The withdrawal cord may be sewn onto the pledget by one or more stitches, such as, for example, between 1 and 20 stitches, such as, for example, 2 stitches, 3 stitches, 4 stitches, 5 stitches, 6 stitches, 7 stitches, 8 stitches, 9 stitches, or 10 stitches. In an non-limiting configuration, the attachment system attaches the deployed cord supply to the substrate using between 1 and 4 stitches before the deployed cord supply is cut to form a withdrawal cord.

The conveyor may comprise an infeed that places substrates, such as pledgets, on the conveyor. The conveyer and the infeed may be adjusted to space the pledgets apart based on the withdrawal cord setting. The conveyer may feed the pledget to a sewing apparatus. The conveyor may be timed so that the number of pledgets is timed with the number of withdrawal cords to have one pledget for every one withdrawal cord.

The metering system, transfer member, cutting apparatus, and conveyor may work in unison to deliver a withdrawal cord to a substrate. The metering system, transfer member, cutting apparatus, and conveyor may work in unison to deliver multiple withdrawal cords to a substrate. In a non-limiting configuration, the metering system, transfer member, cutting apparatus, and conveyor may be phased to control the location of the withdrawal cord on the substrate. Phasing the metering system, cutting apparatus, transfer member, and conveyor allows a withdrawal cord to be attached to a pledget within an acceptable error of a predetermined location on the pledget.
